Hi Fredo! Thank you for your reply.

I have no idea how to do what you ask me to... but i traid.

• download "ruby code editor" in extantion warehouse and copy/past like your instructions.
  What i got:
• Ruby says: #Sketchup::Selection:0x0000019c4093a840

Anyway answering your queston:
Yes, I do have other plugins instaled at this time, because I reintaled all yesterday AFTER clean up averything and delet all the plugins I use to have.
But, important to say, when I "started again" the first plugin I instaled was FredoLib. And when the error happened, there was only FredoLib and TopShaper installed, besides the native Sket plugins.

AND an important information for you:
I tryed this morning JointPushPullClassic_v2.2a (the old version).
And it seans to work well.

Hi everyone! Happy new year!

I'm trying to work with Fredo plugins without success. I would like to request help.

Important informations:
At first we had:

• SKP 2021 pro (PT language)
• Windows 10 (PT language)

This error happened during installation in several plugins: JointPushPull, TopoShaper, JointPushPull, FredoScale...

*[pre:3io0lz19]Error starting up plugin (creating menus and icons) undefined method `add_item´form nil:NilClass [in lib6traductor.rbe - # ´add_command(): line 1389]

After talking to some colleagues and reading almost this entire forum...

• I uninstalled SKP (language PT) deleting everything, including the plugins folder, temporaries, everything, everything, everything...
• I up dated windows for the lasted versin (11) avalible
• I downloaded SKP (EN language) at Trimble website
• I installed it again as an admin
• I downloaded FredoLib - December 21st version
• I installed FredoLib through the extention manager

At this time, I only had the original SKP plugins and libfredo installed.

• SKP 2021 pro (EN language)

• Windows 11 (PT language)

• I downloaded JointPushPull at SU

• I installed it through the extention manager

• main menu appeared immediately

• closed and opened SKP
  No error. But, the buttons don't work. The auxiliary menu that should appear does not appear.

I thought the problem could be the firewall, blocking pop up windows.

• I disabled the firewall (McAfee)

• I reset the computer
  But unfortunately the buttons still have no function.

• I downloaded TopoShaper from the SU website

• Installed through the extention manager
  And the previous error reappeared.

Tried the same with JointPushPull and FredoScale and same error.

Any idea what might be going on or if we're doing something wrong? =/
